B&W Roll Wheel™ Pulverizer Modifications Improve Performance and Reliability Hi-spin stationary classifier The hi-spin stationary classifier retrofit is for louver sections originally supplied with straight top housing pulverizers. This modification allows the same fineness with less air resistance compared to the original classifier.
Ensure optimum arrangement of the mill throat and the coal flow path to improve mill performance. * *Close tolerances. Pulverized coal mills with throats that are too wide will have corresponding low throat velocity in the mill grinding zone that contributes to excessive coal rejects and fires. This is an example of an oversized mill throat.
All coal pipes (and flows to all of the burners from each respective pulverizer) should be balanced and within +/- 2% of the mean flow. Perform a seal air check. Begin the normal pulverizer start sequence. Once normal coal flow is applied to the mill, a full mill test should be conducted. This should include isokinetic coal sampling and dirty ...

In addition, coarser particles reduce burner stability at low load. Air flow distribution at the mill throat, as well as inside the mill, significantly influences the mill performance in terms of separation, drying, coal/air flow uniformity at the mill outlet, wear patterns and mill safety.
High temperature throat plates To maintain the required mass flow of air per pound of coal, the higher temperature inlet air causes higher volume flow and higher air velocity entering the grinding zone. The higher velocity will upset coal circulation within the pulverizer, which can lead to mechanical damage and reduced reliability.
